HYPER localized hyperthermia – early results
2020
In magnetic fluid hyperthermia (MFH), Magnetic Nanoparticles (MNPs) dissipate heat when exposed to alternating magnetic fields (AMF). MFH is used for targeted energy deposition for targeted drug-delivery or cancer therapy. To avoid heat deposition in all areas with high particle concentration, a gradient field featuring a field-free area (FFR) can be utilized to isolate heating a target region. In this work, we present preliminary results with a localized hyperthermia system, HYPER, that features a mechanically actuated gradient that enables adjusting the heating region’s size and position. The size of the heating region in our prototype is verified by measuring the full width at half maximum (FWHM) of the specific absorption rate (SAR) point spread function (PSF) and compared to a theoretical heating model.
